java中Calendar类用法

package test;

import java.util.Calendar;

public class CalendarTest {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		//获得日历对象
		Calendar c = Calendar.getInstance();
//		System.out.println(c.get(Calendar.YEAR));
//		System.out.println(c.get(Calendar.DATE));
		c.setFirstDayOfWeek(Calendar.MONDAY);
		//显示当前的日期和各个分量
		display(c);
		
		//设置日期和时间
		c.set(2012, 11, 23);
		c.set(Calendar.HOUR, 10);
		c.set(Calendar.MINUTE, 4);
		c.set(Calendar.SECOND, 54);
		System.out.println("更新后的时间：");
		display(c);
		
		//调整日期和时间
		c.add(Calendar.DATE, 10); //意思是把当前日期加上10天
		c.add(Calendar.HOUR_OF_DAY, 10);//意思是把当前时间加上10个小时
		
	}
	
	public static void display(Calendar c){
		String month[]={"1月","2月","3月","4月","5月","6月","7月","8月","9月","10月","11月","12月"};
		String days[]={"星期日","星期一","星期二","星期三","星期四","星期五","星期六"};
		System.out.print("日期：");
		System.out.print(c.get(Calendar.YEAR )+"年");
		System.out.print(month[c.get(Calendar.MONTH)]);
		System.out.print(c.get(Calendar.DATE )+"日 ");
		System.out.println(days[c.get(Calendar.DAY_OF_WEEK)-1]);
		System.out.print("时间：");
		System.out.print(c.get(Calendar.HOUR)+":");
		System.out.print(c.get(Calendar.MINUTE)+":");
		System.out.println(c.get(Calendar.SECOND));
